NullPointerException during motif generation

[steplica]

During motif generation (the /tasks/updatemotifs endpoint), we get 85 NullPointerExceptions in GenerateMotifService.java on the line res.setResidueChainName(group.getResidueNumber().getChainName());.

We should investigate some of these cases to see what the cause is. If the cause is out of our control, we should gracefully handle this situation so our logs don't explode with 85 stack traces.

@jmiller656 do your changes related to motif generation bug fixes address this case?
